Hello
I am trying to set up access the serial terminal I set up on my single board
computer (ALIX2) running FreeBSD. I followed the configuration provied in
the Terminal section of the Handbook, subsection 24.3.2.1 "Adding an Entry
to /etc/ttys forced init with the
#kill -HUP 1.
The question is; if the login prompt is to appear where would it appear? Would
it be one of the virtual terminals? Do I need to use cu, tip, or minicom?
When I use cu program
# cu -l cuad1
I receive a message
Connected
But I do not receive a prompt.
The getty process is running
# ps -axwww | grep getty
47126 ?? I 0:00.00 /usr/libexec/getty std.19200 ttyd1

My /etc/ttys file
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
ttyd0 "/usr/libexec/getty std.9600" dialup off secure
ttyd1 "/usr/libexec/getty std.9600" dialup on secure
ttyd2 "/usr/libexec/getty std.9600" dialup off secure
ttyd3 "/usr/libexec/getty std.9600" dialup off secure
My setting on the single board computer
/etc/tty
ttyd0 "/usr/libexec/getty std.9600" dialup on secure
/boot/loader.conf
console="comconsole"
comsonsole_speed="19200" #This may be the problem
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/term.html
I am going to change the /boot/loader.conf, and hope the terminal login
appears.
Thank you
Aaron
